Two-port parameter ( h_{12} ), also known as the reverse voltage gain or the transfer parameter, represents the relationship between the output voltage ( V_2 ) and the input current ( I_1 ) in a two-port network. Specifically, it is defined as ( h_{12} = -\frac{V_2}{I_1} ) when the output port is open-circuited (i.e., ( I_2 = 0 )). In practical terms, it indicates how changes in the input current affect the output voltage, highlighting the interdependence of input and output in the network's behavior.

Briefly explain 'h-parameter model' for BJTs?
h-parameter used to find the input and output impedence of the two port network. suppose if u connect a high load at the output port then u should take care that no current from the device will attack the network, to determine that we should know what is the impedance of the circuit.
What are the uses of h parameter?
h parameters are the two port parameters , a two port parametres has two ports or four terminals two for input and two for output. In general the convention is to take current at both input and output ports into the network.for a linear network (passive elements like current source, voltage source and resistors donot change their value during the performance of circuit), we can write the voltage and current as a linear funcion of input and output parameters. especially these h-parameters are widely used in electronics cirtcuits rather than electrical circuits , the major advantage of these is we need not follow the whole tedious procedure again and again to calculate the input and output parameters just by knowing the h-parameters these values are found by direct substitution , hence one can save a lot of time by using these parameters and we come across different errors while calculation of the output parameters, if we use these h parameters only one confident and neat calculation is sufficient
What are h parameters of a transistor?
Answerthe h parameter or the hybrid parameters of a transistor helps us to analyse the amplifying action of transistor for small signal .it is necessary for practical purposes.In generally there are four type of h parameter.these are :h11h12h21h22
What assumption are taken to analyze a transistor using h-parameter?
The output conductance is assumed to tend to infinity and the collector current is assumed to be equal to beta multiplied by the base current.
What are the salient features of a hybrid parameter?
Hybrid parameters, often used in the analysis of two-port networks, combine both voltage and current characteristics. The key features include the representation of input and output characteristics using a mix of voltages and currents, typically denoted as h-parameters. They allow for simplification in circuit analysis by expressing the relationship between input voltage and current, and output voltage and current in a compact form. Additionally, hybrid parameters are particularly useful in modeling transistors and amplifiers, as they facilitate small-signal analysis.

What is the application of z parameter?
Impedance parameters or Z-parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering to describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small signals. They are members of a family of similar parameters used in electronics engineering, other examples being: S-parameters,[1] Y-parameters,[2] H-parameters, T-parameters or ABCD-parameters.[3][4]The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the input currents, output voltages and the Z-parameter matrix is given by: .whereFor the general case of an n-port network, it can be stated that

When h has the value of twelve culculate five h minus two?
5h means five times h - the times symbol is not written as it can be confused with a letter 'x': h = 12 → 5h - 2 = 5 x 12 - 2 = 60 - 2 = 58
